Problem with viewport

[Dolox75]

So yesterday for no apparent reason everything in my viewport disappeared except from the Sky as you can see in the image. Going into the top view, or any other view I can see the meshes, it is in perspective that nothing shows. Only sometimes when hovering over with the mouse you can sort of see the collision boxes.
Pressing F with mesh selected does nothing

I’m wondering if you have the sky selected with the other objects, somehow.

When you select an object, does it just say ‘1 selected’ in the outliner?

Have you grouped things?

[Dolox75]

I can confirm that it shows “1 selected” in the outliner

Also, no, I haven’t grouped things

Thanks

Ok, bizarre. Hard to say. Maybe reset the editor layout and try again?

Window → Load layout → Default editor layout

Nothing… The weird thing is that the meshes are there because if I select them in the outliner I can see the collision in the perspective viewport…

If it’s small new project, you can upload it and I’ll take a look. But I’ve run out of ideas, I’m afraid

Thanks for your time, but I’m not allowed to share this project. I might have to start all over again ffs
